TOY AIRPLANE ASSEMBLY HAVING A
MICROPROCESSOR FOR ASSISTING FLIGHT - RC plane construction

Department Of Aeronautical Engineering Students

ABSTRACTof Thesis: A toy airplane assembly is provided that is easy to fly, inexpensive, and durable. The toy plane assembly includes a plane having a radio receiver and a microprocessor. Batteries housed in the fuselage power the printed circuit board to which the microprocessor and radio receiver are attached. The radio receiver receives signals from a handheld remote control radio transmitter and are transmitted to the microprocessor. The microprocessor decodes the signals and, in response thereto, distributes power to the motors for driving the propellers. All movement of the plane is controlled by the microprocessor, thereby providing microprocessor assisted flight. The plane fuselage is a one-piece molded part, made of a foam material to provide a durable plane.

Title: ANALYSIS OF THE AERODYNAMICALLY DEPLOYABLE WINGS AND PAYLOAD SUPPORT STRUCTURE OF THE MONO TILTROTOR

Department Of Aerospace Engineering

Abstract of Thesis: The Mono Tiltrotor (MTR) is a new VTOL concept, proposed to meet heavy lift rotorcraft requirements. The premise of the MTR is a tilting coaxial rotor system for lifting and propulsion, along with aerodynamically deployable fixed-wings for long-range cruise. The symmetric and controlled self-deployment of these wings is a critical design feature of the MTR concept. To this end, a mathematical model was developed to predict the optimal wing hinge geometry to obtain satisfactory wing deployment. The wing hinge design was then used to design and build a functional model that was tested in the University of Maryland's Glenn L. Martin wind tunnel. The measurements showed that with suitable design features, the symmetric and controlled deployment of the wings is possible using aerodynamic means alone. The mathematical model was then validated against measured wind tunnel data. A Finite Element Methods analysis of the suspended payload support structure was also developed.
